Brightening perovskite LEDs with photonic crystals

All inorganic cesium lead halide perovskite semiconductors exhibit great potential for nanolasers, light emitting diodes and solar cells due to their unique properties, including low threshold, high quantum efficiency and ...

Record efficiency for perovskite-based light-emitting diodes

Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published ...

Shape shifting mirror opens a vista for the future

A team of researchers from JTEC Corporation and Osaka University developed a bimorph deformable mirror that allows for precise shape modification and usage under vacuum, a world first.

Mirage software automates design of optical metamaterials

Sandia National Laboratories has created the first inverse-design software for optical metamaterials—meaning users start by describing the result they want, and the software fills in the steps to get there. The modern design ...

Technique uses well-known dye to watch amyloid plaques in the brain

While amyloid plaques have long been closely associated with mechanisms driving Alzheimer's disease, visualizing how amyloid proteins assemble continues to prove difficult. The nanometer-sized amyloid fibrils are only a fraction ...

Optical toric code platform sets new record

Anyons form the basis for topological quantum computation and error correction, where the topological aspect of anyonic braiding is one of the important features that gives rise to fault tolerance. More qubits to control ...

Physicists create Star Trek-style holograms

Star Trek's famous holodeck is a virtual reality stage that simulates any object in 3-D as if they were real. However, 3-D holographic projection has never been realized. A team of scientists from Bilkent University, Turkey, ...
